Each of our body systems are interconnected and dependent on each other.
Our heart, which is part of our circulatory system, does not beat unless
our brain, which is part of our nervous system, tells it to. Our skeletal
system is dependent on our digestive system for increase in size and strength.
Our muscular system needs our respiratory and circulatory systems to supply
energy in the form of oxygen and nutrients. It takes all the systems for
human growth and development.

Sample some of the following activities to learn more about human body
systems.

1500-1600 pounds!
